Kicking in soccer has been the subject of scientific research for more than 40 years yet review articles summarizing the biomechanical fundamentals of kick optimization as a guide to coaching are scarcely to be found. The current review article aims to bridge the gap between scientific research into the maximal instep kick (including studies employing 3D motion capture and full-body biomechanical modelling) and the application of such research in coaching. It does so by supplying a scientifically founded, coaching-friendly article explaining identifiable characteristics and motor control sequencing that define this skill. Relevant biomechanical factors are identified in a way that should help coaches better develop training programmes and, at the same time, foster better understanding of the skill among athletes. Such information will contribute to both accelerated skill acquisition and, by concomitant gains in skill efficiency, the development of programmes that minimize risk of injury to athletes during training. 相似文献

This article is concerned with early modern interpretations of Hanno the Navigator's Periplus, an ancient travel account of a Carthaginian voyage down the coasts of Africa. The early modern period saw a rise in interest in geographical knowledge, and the ways in which different authors used Hanno's voyage reflects their understanding of the role of geography in conceptualising the world. In these discussions, writers had to negotiate between the confusing portrayals of the voyage in the received classical tradition and new reports brought by voyages of exploration. Here, I will discuss how these syntheses between humanist methods and contemporary travellers' accounts were shaped by the economic and political concerns tied to the first wave of European overseas expansion. Amid this climate, ancient geographical knowledge found pragmatic applications in contemporary issues of navigation, commerce and claims of territorial possession, as well as shaping European perceptions of ‘self’ and ‘the other’. This paper thus seeks to situate humanist practices and classical knowledge within the wider context of overseas voyages and early modern political and economic developments. 相似文献

The article addresses narratives that tell of a member of the 10 Lost Tribes of Israel who comes to the rescue of a Jewish community. The tales were documented at the Israel Folktale Archives, in the second half of the twentieth century, and were told by informants from Morocco and Greece. While it is probably impossible to trace the exact routes of these “cultural possessions”, around and across the Mediterranean, the texts nevertheless provide a glimpse into the ways in which a network of Jewish communities shared a meta-narrative while adapting it to their own regional contexts. Although these tales are quintessentially diasporic, they also provided a platform for negotiating post-exilic identities in the new Israeli national context. 相似文献

The Royal Artillery Factory of Seville in Spain originated from pre‐existing private bronze foundries dating from the 16th century. The paper analyses the stratigraphy of wall cladding in the areas traditionally known as the ‘Old Foundry’ and the ‘New Foundry’, through its characterization by optical microscopy, scanning electron microscopy with energy‐dispersive X‐ray spectrometry (SEM‐EDX), micro‐X‐ray fluorescence (μ‐XRF) and micro‐X‐ray diffraction (μ‐XRD), in order to analyse the metal deposits that have accumulated since the 17th century. The data obtained allowed the verification of the available historiographical information and the location of the original bronze smelting furnaces. The analysis of patinas deposited on the overlapping layers of lime also confirmed that neither the raw materials nor the composition of the alloys used presented any substantial changes. 相似文献

Within the making of Portuguese liberal‐representative democracy, the Portuguese Communist Party became a major actor in local government in urban deprived peripheries, shaping Lisbon's Red Belt. In this article, we analyse the communist discourse on the Portuguese urban question, showing how it politicised the urban as a site of unevenness and deprivation, but simultaneously depoliticised it by refusing to acknowledge it as a proper space for conflict. This historical account leads us to a critical debate with proposals that discuss urban politicisation by ontologising “the urban” or “the political”—we argue that these approaches tend to be less helpful in understanding processes of contingent, partial and inter‐related forms of politicisation/depoliticisation of the urban in itself. In contrast, we argue for a more attentive theorisation on politicisation–depoliticisation of the urban condition as a most valuable path to grasp situated formulations of citizenship and, hence, configurations of political regimes. 相似文献

顺治九年(1652),一艘赴日本贸易的苏州商船回国。史学界对该商船的赴日时间及贸易方式存在争议:一说是1644年赴日,在日本进行了八年的海外贸易;一说是1650年或1651年私自出海,交易完毕后即回国。本文根据明清档案及朝鲜史料对该事件的记载,以及当时中国、东南亚、日本之间的贸易状况进行综合考察,可以肯定该商船是于1644年前往日本,并在日本与交趾之间从事贸易活动。 相似文献

Metallurgical study of seven cast iron artifacts recovered from sites of the former Xiongnu (BC 3rd to AD 1st), Turk (AD 6th to 8th), Khitan (AD 10th to 12th), and Mongolian empires (AD 12th to 15th) shows that the earlier Xiongnu and Turk artifacts were made of cast iron alloys of near eutectic composition. The later Khitan and Mongol objects had greatly reduced carbon content in the range of ultrahigh carbon steel rather than cast iron, and contained more than 0.5 mass % silicon as an alloying element. Inclusions high in sulfur, phosphorus or silicon are also present. These differences suggest that Mongolia experienced a technical transition a few centuries before the establishment of the Mongolian empire, which is in agreement with some written accounts. The microstructures of the cast iron artifacts are compared with the related archaeological and documentary evidence. The results suggest that the use of fossil coal in smelting and the state policy of controlling iron production were the major factors responsible for the transition. 相似文献

雷戈所著《秦汉之际的政治思想与皇权主义》一书,认为从秦朝到汉初的思想史发展阶段是中国思想史上皇权主义意识形态的生成和确立时期,并将其概括为"后战国时代";采用独特的"历史-思想"研究法,从政治制度、官场规则和官吏的政治生活中,挖掘特定时期的政治思想共识,为政治思想史研究开辟了新的路径,并扩大了思想史的资料范围;认为秦汉时期生成的皇权主义秩序,把"天高皇帝远"的制度现实变为"天高皇帝近"的观念实存,实现了对人们思想的可控性,从此,思想成为皇权可以控制和规范的领域,达到了有效的思想专制。这是秦汉以降中国思想史发展的基本特征。该书在研究方法的创新和思想深度的开掘上,都做出了独到的贡献。 相似文献
